Description

The present invention relates to a ceiling-suspended air conditioner (indoor unit) installed on the ceiling of an air-conditioned room by a hanging bolt or the like, and more specifically to an arrangement of a display for displaying an operating state or the like.

The ceiling-mounted air conditioner is installed on the ceiling of the air-conditioned room by hanging bolts or the like. The housing of the ceiling-mounted air conditioner has a front panel (also called a bottom panel) facing the floor of the air-conditioned room, a left side panel, a right side panel and a rear panel, and is often flat. is there.

The inside of the housing is partitioned by a partition plate into a heat exchanger room in which the indoor heat exchanger and the drain pan are stored and a blower room in which the blower fan (sirocco fan) is stored.

Normally, the heat exchanger room is arranged on the front panel side, the blower room is arranged on the rear panel side, the air outlet is provided in front of the housing on the heat exchanger room side, and the bottom side of the blower room side. Is provided with an air suction port. A suction grill having an air filter is attached to the air suction port, and a wind direction plate is provided at the air outlet.

According to this, by operating the blower fan, the indoor air is sucked into the housing from the air suction port, and after heat exchange with the refrigerant through the heat exchanger, it is directed to the room from the air outlet in front of the housing. Is blown out.

The air conditioner (indoor unit) is provided with an indicator that displays the operating status of cooling, heating, dehumidification, timer operation, and the like. A display is also provided in the ceiling-mounted air conditioner, but in many cases, the display is arranged on the front panel on the front surface of the main body having good visibility (see, for example, Patent Document 1).

Since the ceiling-mounted air conditioner itself is large, the front panel is also large. If the large front panel is made of synthetic resin, there will be molding problems such as sink marks. Therefore, for example, decorative steel plates (sheet metal parts) are used for the front panel, but they are large and heavy when the display is attached or replaced. There is a problem that it is difficult to work at the installation site because it is necessary to remove the front panel.

Further, the display is an optional part, and when the display is not required, a name plate (plate) displaying, for example, a brand name or a model name is fitted in the mounting location of the display.

However, since this type of name plate is larger than the display in the sense that it hides the mounting location of the display, it is too conspicuous than necessary and is a factor that impairs the sense of unity of the appearance design.

"overall structure"
First, referring to FIGS. 1 to 5, the ceiling-mounted air conditioner 1 according to the present invention is an indoor unit installed on the ceiling of an air-conditioned room, and includes a flat housing 10. In the description of this embodiment, the upper side (upper surface side), the front side (front side side), the rear side (rear surface side), the side side (side surface side), and the lower side (bottom surface side) are based on FIG. ) Refers to the front side of the page.

The housing 10 is suspended from the ceiling of the air-conditioned room (indoor) by a hanging bolt or the like (not shown). Although not shown, it may be installed near the ceiling by being supported by an inverted L-shaped hanger device as a wall-mounted installation.

The housing 10 includes a top panel (top plate) 11 facing the ceiling surface, a left side panel (side plate) 12L, a left side panel (side plate) 12R, and a front panel (front plate) 13. , A rear panel (rear plate) 14 is provided.

When it is not necessary to distinguish between the left side panel 12L and the left side panel 12R, the side panel 12 is generically used. In FIGS. 1 and 2, the side panel 12 is not visible because it is covered with the cosmetic side cover 15 (15L, 15R). Each of these panels 11 to 14 is made of sheet metal, and in particular, a decorative steel plate is used for the front panel 13, but each of the panels 11 to 14 may be made of synthetic resin.

As shown in FIG. 3, the inside of the housing 10 is divided into a heat exchanger chamber 17 and a blower chamber 18 in the front-rear direction by a partition plate 16. An indoor heat exchanger 171 and a drain pan 172 are housed in the heat exchanger room 17.

The drain pan 172 is made of Styrofoam, for example, and is arranged below the indoor heat exchanger 171 as a dew tray. The front panel 13 is arranged along the bottom surface of the drain pan 172 as a decorative cover. As will be described later, the front panel 13 is removable and is removed during maintenance (for example, cleaning) of the drain pan 172.

An air outlet 20 is provided in front of the heat exchanger chamber 17 (on the front end side of the housing 10). The air outlet 20 is a horizontally long opening, and a vertical wind direction plate 21 is provided inside the air outlet 20. Further, a left and right wind direction plate 22 is provided behind the vertical wind direction plate 21.

Inside the blower room 18, a sirocco fan 181 as a blower is housed. In this example, as shown in FIG. 4, four sirocco fans 181 are used. The outlet of the fan case sink 182 of the sirocco fan 181 penetrates the partition plate 16 and enters the heat exchanger chamber 17.

The bottom surface of the blower chamber 18 is an air suction port 30. A suction grill 31 having an air filter 32 is provided in the air suction port 30. The suction grill 31 is arranged so as to be in contact with the rear end of the front panel 13, and the front panel 13 and the suction grill 31 form the bottom surface of the housing 10. The rear end 311 side of the suction grill 31 is pivotally supported by the lower end of the rear panel 14, and can be rotated and opened as shown in FIG.

By the operation of the sirocco fan 181 the indoor air is sucked into the blower chamber 18 through the air filter 32 of the suction grill 31, blown out from the fan case sink 182 into the heat exchanger chamber 17, and becomes a refrigerant in the indoor heat exchanger 171. After the heat is exchanged, the air is blown out from the air outlet 20 toward the room to air-condition the room.

<< External shape of housing (side cover) >>
Cosmetic side covers 15L and 15R are attached to the side panels 12L and 12R, respectively. Since the side covers 15L and 15R are symmetrical, they are collectively referred to as the side cover 15 when it is not necessary to distinguish them.

With reference to FIGS. 6A and 6B, when the side cover 15 is viewed from the floor surface side, the housing 10 looks thin and the volume feeling is reduced. Therefore, the side cover 15 has the upper region 151 on the ceiling side and the floor surface side. It is partitioned into the lower area 152 of the.

The side cover 15 has a dogleg-shaped outer shape in which the boundary portion 153 of the upper region 151 and the lower region 152 projects outward of the housing 10. That is, the left side cover 15L is formed in a dogleg shape so that the boundary portion 153 protrudes to the left side, and the right side cover 15R has a cross section such that the boundary portion 153 protrudes to the right side. It is formed in a character shape.

According to this, when looking up at the housing 10 installed on the ceiling, all or a part of the upper region 151 is hidden by the lower region 152, and the housing 10 looks thin. Further, in the case of wall suspension installation, the hanger portion becomes difficult to see, so that the housing 10 can be made to appear to be floating.

In order to further enhance these effects, it is preferable that a step portion 154 having a predetermined width (for example, about 12 mm) is formed along the boundary portion 153 on the upper region 151 side of the boundary portion 153. According to this, since the lower region 152 is arranged outside the housing 10 than the upper region 151, the upper region 151 becomes more difficult to see.

The lower region 152 exhibits a strip-shaped surface, and is formed so as to be connected in a series from one side cover 15R on the right side, for example, through the front cover portion 110 of the top panel 11 to the side cover 15L on the other left side.

With reference to FIG. 6, in the front cover portion 110, air is blown from the terminal portion 111 in which the boundary portion 153 and the step portion 154 abut against the top surface panel 11 and disappear as the lower region 152 wraps around to the top surface panel 11. It is a portion extending to the front end 10a of the housing 10 on the outlet 20 side, and corresponds to the upper surface of the air outlet 20.

Preferably, the front cover portion 110 of the top panel 11 is provided with an inclined surface having a downward slope from the end portion 111 toward the front end 10a, and the lower region 152 of the side cover 15 is above the air outlet 20. As shown in FIG. 7, it is preferable to bend the corner portion C1 from the side cover 15 of the lower region 152 to the front cover portion 110 so as to have a first curved surface having a large curvature to reduce the corners.

According to this, the lower region 152 is grasped as a series of strip-shaped surfaces with a sense of unity by the visual effect, the volume feeling of the housing 10 and the feeling of protrusion to the side can be reduced, and the effect of making the housing 10 appear more compact than the actual width is achieved. Will be done.

In order to further emphasize this effect, as shown in FIG. 7, the corners 201 of the air outlet 20 and the corners 211 of the vertical wind direction plate 21 are also covered from the side cover 15 to the front cover 110 of the lower region 152. It is preferable to have a curved surface having the same curvature as the corner portion C1 leading to.

Further, in order to express the feeling that the strip-shaped lower region 152 also wraps around to the rear panel 14 side, the lower region 152 of the side cover 15 is curved so as to wrap around to the rear panel 14 side.
As shown in FIG. 2, it is preferable that the corner portion C2 on the rear end side of the lower region 152 has a vertically long second curved surface having a predetermined curvature. According to this, when looking up from the front, the effect of making the corner portion C2 on the rear end side of the lower region 152 appear to have a curved surface larger than the actual one is produced.

"display"
Next, with reference to FIGS. 8 and 9, the arrangement of the display 40 for displaying the operating state (operating state of cooling, heating, dehumidification, timer operation, etc.) of the ceiling-mounted air conditioner 1 will be described. ..

The display 40 is an optional part, and if the display 40 is not required, for example, a name plate (plate) 430 displaying a brand name, a model name, etc. will be fitted in the mounting location of the display 40. By attaching the display 40 to the flange portion 155 of the side cover 15, those operations can be easily performed only by removing the side cover 15.

The display 40 includes a display main body 410 having a control board for display and the like, and a removable display cover 420 attached to the display surface side of the display main body 410. The display main body 410 is equipped with a number of light emitting diodes 411 corresponding to the display items, and a translucent plate is used for the display cover 420, for example, at a position corresponding to the light emitting diodes as a pictogram display. A plurality of icon marks 421 are drawn.

The display main body 410 is fitted into a part of the flange portion 155 and fastened with screws, but it is preferable that the display main body 410 is arranged at a position closer to the rear panel 14 side of the flange portion 155 away from the air outlet 20. Particularly preferably, unlike the air outlet 20, the suction grill 31 does not have a moving part such as a wind direction plate, and it is difficult to see the line of sight. Therefore, the display 40 may be arranged beside the suction grill 31.

Further, even in the pictogram display (icon mark 421), it is preferable that the pictograms are arranged side by side parallel to the horizontal rail 313 of the suction grill 31 instead of being arranged vertically when viewed from the front side of the housing 10. According to this, there is no difference in the visibility of the pictogram display when viewed from the front side of the housing 10. In addition, it is possible to unify the design.

《Electrical equipment box》
With reference to FIG. 10, in the present invention, the electrical component box 50 is provided on the outer surface side of any one of the side panels 12L and 12R. Specifically, it is arranged in the space S (see FIG. 6B) formed by the side panel 12 and the side cover 15. According to this, by removing the side cover 15, the electrical component box 50 can be easily accessed, for example, parts replacement and the like can be easily performed, and workability is improved.

Preferably, it is arranged on the side panel 12 on the side close to the display 40, and in this embodiment, on the side panel 12R on the right side. According to this, the wiring length between the electrical component box 50 and the display 40 is shortened, and it is not necessary to route long wiring in the housing 10.

Although not shown, the indoor heat exchanger 171 is provided with a pipe connecting portion of a refrigerant pipe at one end on the left side or the right side. Since the pipe connection portion is provided with a pipe temperature sensor, an electronic expansion valve, etc. (both not shown), more preferably, the pipe connection portion of the indoor heat exchanger 171 is also a side surface on the side where the electrical component box 50 is provided.

Can be done. The connection pipe P includes a gas side pipe and a liquid side pipe.

According to the present invention, as described above, the electrical component box 50 is arranged not between the sirocco fan 181 and the rear panel 14, but in the space S formed by the side panel 12 and the side cover 15. As shown in FIG. 3, the space between the sirocco fan 181 and the rear panel 14 in the blower chamber 18 can be used as the piping space 180 through which the connecting pipe P is passed.

Here, assuming that the pipe connecting portion of the indoor heat exchanger 171 is arranged on the right side, as shown in FIG. 10, the connecting pipe P is a rear panel along the right side panel 12R from the pipe connecting portion. Heading toward the right corner portion 141R of 14, one of top-out, back-out, and side-out (right) is selected from there. In FIG. 10, back-out is selected.

On the other hand, when the connecting pipe P is pulled out from the left corner portion 141L, the connecting pipe P is pulled out from the right corner portion 141R and then bent at a substantially right angle toward the left corner portion 141L, and is bent toward the left corner portion 141L at a substantially right angle to the sirocco fan 181 and the rear surface. It passes through the piping space 180 between the panel 14 and reaches the left corner portion 141L. Then, one of top-out, back-out, and side-out (left) is selected for the connection pipe P.

In order to facilitate this pipe pulling operation, as shown in FIG. 11, the right corner portion 141R and the left corner portion 141L are each provided with a pipe pulling out portion 190 capable of pulling out in three directions. FIG. 11 shows a mode in which the connecting pipe P is laterally pulled out (Ps) and rearward (Pb) from the right corner portion 141R, and a mode in which the connection pipe P is rearranged (Pb) from the left corner portion 141L.

As shown in FIG. 13, the pipe drawer portion 190 of the left corner portion 141L has a first drawer portion 191 for lateral protrusion provided on the side panel 12 and a second drawer portion 191 for rearward protrusion provided on the rear panel 14. A drawer portion 192 and a third drawer portion 193 for raising the top surface panel are included.

According to this embodiment, a holding metal fitting 34 is provided between the beam metal fitting 33 and the top panel 11 to hold the connecting pipe P passing through the piping space 180 between the sirocco fan 181 and the rear panel 14. ..

As shown in FIGS. 4 and 5, the blower chamber 18 side of the side panel 12 is largely hollowed out in a U shape for attaching the support member of the sirocco fan 181 and for the first drawer portion 191 for lateral protrusion. Since the cage strength is insufficient, each side panel 12 (12L, 12R) is provided with a removable reinforcing stay 35 for increasing the mechanical strength of the housing 10.

The reinforcing stay 35 is a component that may be removed from the side panel 12 after the ceiling-mounted air conditioner 1 is installed on the ceiling. Therefore, in the present invention, the reinforcing stay 35 is used as the holding metal fitting 34 to make effective use of the reinforcing stay 35.

《Hanging the front panel》
The front panel 13 is removed during maintenance of the indoor unit, for example, during maintenance of the drain pan such as removing the drain pan 172 from the housing 10 and cleaning it. Due to its weight, the front panel 13 may not be fully supported by one person when it is removed and attached. Therefore, in the present invention, a configuration is adopted in which the front panel 13 can be suspended from the housing 10.

With reference to FIGS. 3, 13 to 16, an inverted L-shaped angle portion 135 is formed at the rear end 131 of the front panel 13 on the suction grill 31 side. The angle portion 135 includes a vertical plate portion 135a that rises vertically from the rear end 131 of the front panel 13, and a horizontal plate portion 135b that is bent at a right angle from the upper end of the vertical plate portion 135a.

A flange portion 161 bent at a substantially right angle is integrally formed at the lower end of the partition plate 16. One end of the beam fitting 33 is attached to the flange portion 161. When the front panel 13 normally covers the bottom surface of the drain pan 172, the horizontal plate portion 135b is in contact with the lower surface of the flange portion 161 as shown in FIG.

With reference to FIG. 14, a bearing fitting 137 having a pair of left and right coaxial bearing grooves 137a and 137a is fixed to the bottom surface side of the horizontal plate portion 135b by welding or the like. The hanging hook 60 is attached to the rear end 131 of the front panel 13 by the bearing fitting 137.

The hanging hook 60 is made of a round bar steel wire. The hanging hook 60 is bent in a substantially U shape and has a gate shape as a whole. The top 601 and a pair of left and right legs 602,602 in which both ends of the top 601 extend in parallel in the same direction, and the lower ends of the legs 602, 602. It has shaft portions 603 and 603 that are coaxial with each other and are bent in opposite directions.

In the hanging hook 60, the shaft portions 603 and 603 are engaged in the bearing grooves 137a and 137a of the bearing fitting 137 in a state where the top portion 601 is arranged (hooked state) on the upper surface 331 side of the beam fitting 33. ing.

The hanging hooks 60 may be provided at least at two locations on the left and right, preferably for each beam fitting 33. Further, it is preferable that the top portion 601 of the hanging hook 60 and the upper surface 331 of the beam fitting 33 are both horizontal, and according to this, the front panel 13 sways in the left-right direction while the front panel 13 is suspended. Be prevented.

Further, as shown in FIG. 14, the tip 312 on the open side of the suction grill 31 enters the angle portion 135 on the rear end 131 side of the front panel 13 in a flush manner, and is between the front panel 13 and the suction grill 31. There are no gaps in the grill.

As a configuration for that purpose, an engaging hole 136 is formed in the vertical plate portion 135a of the angle portion 135. On the other hand, the suction grill 31 is provided with a plurality of cross rails 313 that are parallel to each other, but the cross rail 313a on the tip side thereof is slidable in the front-rear direction (horizontal direction in FIG. The 313a is provided with an engaging piece 314 that goes in and out of the engaging hole 136 along with the slide.

Further, as shown in FIG. 17, an engaging claw 138 is provided on the inner surface side of the side edge of the front panel 13. The engaging claw 138 is a flat plate made of sheet metal and has a dogleg-shaped hook. On the other hand, on the side edge side of the side panel 12, an engaging hole 123 serving as a counterpart of the engaging claw 138 is provided. The engagement hole 123 is a slit-shaped hole extending in the front-rear direction.

Normally, the front panel 13 is screwed to the housing 10 at several points. If the screw is removed during maintenance of the drain pan 172, the front panel 13 tries to fall away from the drain pan 172, but the engaging claw 135 is caught on the edge of the engaging hole 123, so that the front panel 13 is slightly separated from the drain pan 172. It is held in position (temporarily fixed). When the front panel 13 is opened, the suction grill 31 is opened first, as shown in FIG.

The front panel 13 can slide in the front-rear direction when the screws are removed. Therefore, the front panel 13 is slid to the front side (front side in FIG. 17, left side in FIG. 3) to remove the engaging claw 135 from the engaging hole 123.

As a result, as shown in FIG. 15, the front panel 13 is hung with the hanging hook 60 on the rear end 131 side as a fulcrum. At this time, since the weight of the front panel 13 is applied to the substantially central portion of the housing 10, an unbalanced load is not applied to the housing 10 and the housing 10 is suspended in a well-balanced manner.

Further, as described above, by making the top portion 601 of the hanging hook 60 and the upper surface 331 of the beam fitting 33 both horizontal, the front panel 13 is prevented from swinging in the left-right direction while the front panel 13 is suspended. Will be done.

The front panel 13 is returned to the original position covering the drain pan 172 and screwed after the maintenance of the drain pan 172, but as shown in FIG. 19, a folded-back portion 133 is formed on the tip end side of the front panel 13. At the same time, a recess 173 into which the folded-back portion 133 is fitted is formed on the drain pan 172 side corresponding to this.

A locking projection 174 is formed in the recess 173 so that the folded-back portion 133 of the front panel 13 can be detachably hooked. As described above, the front panel 13 can slide in the front-rear direction when the screw is removed.
